创建一个多维数组 - 有比这更好的方法

Question

我有这个代码

        foreach ($objWorksheet->getRowIterator() as $row) {

            $output[] = array();

            //adding a blank array to the end doesn't seem to 
            //advance the array pointer so do it manually.
            $test = end($output); 

            $cellIterator = $row->getCellIterator();
            foreach ($cellIterator as $cell) {
                //specifically this bit
                $output[key($output)][] = $cell->getValue();
            }
        }

但我不喜欢我如何使用当前密钥

$output[key($output)][] = $cell->getValue();

有更好的方法吗？

你为什么不使用另一个变量？

foreach ($objWorksheet->getRowIterator() as $row) {
    $cells = array();
    foreach ($row->getCellIterator() as $cell) {
        $cells[] = $cell->getValue();
    }
    $output[] = $cells;
}
